RK in the house. 3-1/2" longer front strut forks, 2" poly spacers in the rear. Going on 4 months with no issues. It cost a bit more, but I got a good deal with free shipping. You could spend a little less cash and get the same amount of lift. In hindsight, I wouldn't choose one over the other, inluding the RK.

just ordered me the RC 2" lift... 150 for 2", with steel spacers rather than plastic... cant beat that. Also ordered me a set of bilsteins to throw on there... should be a good all around lift... gonna roll on a set of 265/70/r17 BFG ATKO's with 1.5" spacers. Originally i was going to go with the RK lift but the place i ordered it from was back ordered and didnt tell me it was going to take a bit longer until 5 days after i placed my order .. hmph! hopefully the tires wont rub, but it will be a nice budget lift and so far with all the reviews/comments/etc i've read on this board it seems like everything is going to be ok.
